Pre-Assignment Details

Significant events and approaches for the overall study
following participant enrollment, but prior to group assignment

Of the 18729 subjects enrolled in the study, 64 subjects were not vaccinated. Within the 18665 subjects vaccinated, 21 subjects from 1 center were excluded from all analyses because of potential data discrepancies identified at this center. As a result, a total of 18644 subjects are reported as started in the participant flow.

Explanation of how the number of participants for analysis was determined.
Includes whether analysis was per protocol, intention to treat, or another method.

Number of Subjects With Histopathologically-confirmed Cervical Intraepithelial Neoplasia (CIN)2+ Associated With HPV-16 and/or -18 Cervical Infection in Subjects HPV DNA Negative and Seronegative at Baseline or Overall (Any Serostatus at Baseline) [ Time Frame: Up to the moment when 36 cases of CIN2+ lesions associated with HPV-16 or HPV-18 infection had been detected, including at least 15 cases of CIN2+ associated with HPV-18 infection. Mean follow-up was 34.9 months post-dose 3 ]

Number of Subjects With Histopathologically-confirmed Cervical Intraepithelial Neoplasia (CIN)1+ Associated With HPV-16 or HPV-18 Detected Within the Lesional Component of the Cervical Tissue Specimen [ Time Frame: Up to the moment when 36 cases of CIN2+ lesions associated with HPV-16 or HPV-18 infection had been detected, including at least 15 cases of CIN2+ associated with HPV-18 infection. Mean follow-up was 34.9 months post dose 3 ]

Number of Subjects With Persistent Infection (6-month Definition) With HPV-16 or HPV-18 [ Time Frame: Up to the moment when 36 cases of CIN2+ lesions associated with HPV-16 or HPV-18 infection had been detected, including at least 15 cases of CIN2+ associated with HPV-18 infection. Mean follow-up was 34.9 months post dose 3 ]

Number of Subjects With Persistent Infection (6-month Definition) With Oncogenic HPV Types [ Time Frame: Up to the moment when 36 cases of CIN2+ lesions associated with HPV-16 or HPV-18 infection had been detected, including at least 15 cases of CIN2+ associated with HPV-18 infection.

Number of Subjects Reporting Persistent Infection (12-month Definition) With HPV-16 or HPV-18

Measure Description

Persistent cervical HPV infection (12-month definition) was defined as the detection of the same HPV type (by PCR) over a 12-month interval (evaluations were planned at approximately 6-month intervals).

Overall: subjects HPV DNA- at Month 0 and Month 6 for the corresponding HPV-type and regardless of initial serostatus at baseline

Time Frame

at Month 48

Population Description

Explanation of how the number of participants for analysis was determined.
Includes whether analysis was per protocol, intention to treat, or another method.
Also provides relevant details such as imputation technique, as appropriate.

Analysis was performed on the According-to-Protocol (ATP) cohort for efficacy, which included all evaluable subjects, who had received 3 doses of study vaccine and who had a normal or low-grade cytology (i.e. negative or ASC-US or LSIL) at Month 0. All subjects had at least 10 months of follow-up after Month 12.

No statistical analysis provided for Number of Subjects Reporting Persistent Infection (12-month Definition) With HPV-16 or HPV-18
